VENTILATO R.

SPECIFICATION forming part of Letters Patent No. 376,094, dated January10, 1888. Application filed October 4, 1887. Serial No. 251,460. (Nomodel.)

To all whom it may concern.- 7

Be it known that I, SAMUEL YVESLEY, HURL- BURT, a citizen of the UnitedStates, residing at Oreston, in the county of Union and State of Iowa,have invented a new and useful Improvement in Ventilation, of which thefollowing is a specification.

My invention relates to an improvement in ventilators for use inconnection with mattresses, pillows, bolsters, and analogous articles;and it consists in the construction, and arrangement of the partsthereof, which will be more fully hereinafter -described, and

ment shown in connection therewith. Fig. 2

is a similar view of a pillow with my improvement in'connectiontherewith. Fig. 3 is a detail perspective view of my improved device.

A indicates a central perforated reservoir,

preferably rubber, which is constructed of such a size as will producethe most beneficial and necessary results, and proportionately tothearticle with which it is mounted. To the sides of this reservoir Atubes B are secured, which are formed with perforations Z), and whichproject outwardly through the article in which the device ismountedthrough the sides thereof, and suitable disks, 1), of bone or othermaterial, are secured on the said outer ends of said tubes, so that theair may readily enter the said tubes. As the reservoir A is compressedby the weight thereupon and allowed to expand by the movement of theweight, the air will be drawn inward through the tubes or pipes B, and,passing through the apertures b, a circulation of air within themattress, pillow, or bolster is established. The normal condition ofthepipes and reservoir, however, will permit the entrance of airtherethrough, and purification and healthfulness will necessarily be theultimatum of the use of my improvement.

Heretofore it has occasioned considerable trouble and inconvenience tocleanse and purify mattresses, pillows, bolsters and analogous articles,and at best the purification was only partially successful.

By my improvement a continuous circulation of air is established, andthe result greatly beneficial to healthful sleep.

The utility of my device being obviously apparent, it is unnecessary tofurther enlarge uponthe same. .7

Having thus described my invention, what I claim as new is l. Amattress, pillow, bolster, or other analogous article provided with aventilator consisting of a series of perforated ventilatingtubes havingtheir outer ends accessibly arranged relatively to the surrounding airand connected at their inner ends with a common interiorly-situated andperforated reservoir of elastic material, substantially as described.

2. The combination, with a mattress, of the central expansibleperforated reservoir, A, the tubes B, projecting laterally therefrom andprovided with perforations b, the outer ends of said tubes projectingoutside of the mattress, and disks b, surrounding the outerends of saidtubes Bto keep them outside of the mattress, substantially as described.

3. In a mattress, bolster, pillow, or other analogous article, anexpansible and retractible ventilatingframe arranged interiorly andconsisting of a perforated reservoir, and one or more perforated tubeshaving their inner ends connected to the perforated reservoir and theirouter ends projecting outside the mattress, bolster, pillow, or thelike, substantially as and for the purpose described.

In testimony that I claim the foregoing as,
